EDWARD P. \VAGGONER, OF SYRACUSE, NEW YORK, ASSIGNOR OF ONE-HALF TO THE PIERCE BUTLER AND PIERCE MANUFACTURING COMPANY, OF

BOILER.

SPECIFICATION forming part of Letters Patent No. 416,129, dated November 26, 1889.

Application filed November 19, 1888. Serial No. 291,218. (N'dmodeh) To aZZ whom it may concern.-

Be it known that I, EDWARD P. WAG GONER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Boilers, of which the following, taken in connect-ion with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in heaters, and has for its object the production of a simple and effective heater the peculiar and novel construction of which shall produce or raise steam much more quickly and in a greater quantity in proportion to the amount of fuel used than has been possible with de* vices heretofore constructed, and shall also allow the heater having these special features of advantage to be constructed at a minimum cost of expense.

To this end my invention consists in a heater composed of separate sections, with water-connections between the sections, projections or corrugations on both sides of one or more of these sections taking the place of fines and conducting the products of combustion against the surface of these corrugations and insuring their contact with an unusual amount of heating-surface, baffle-plates between the heater and its outside casing turning the heat around the outside surface of the heater-sections, and doors extending through the outside casing of the heater, allowing every part to be thoroughly cleaned and insuring constantly a ready and uninterrupted draft for the products of combustion.

tion of the heater, illustrating particularly the construction and relative arrangement of the heater-sections, the corrugations thereon, and

the means for thoroughly cleaning the outside of these sections. Fig. 3 is a top plan view, partly in section, of the bottom or first section of the heaten. Fig. 4 is a top plan view, partly in section, of the next or second section of the heater. Fig. 5 is a top plan view, also partly in section, of the third section of the heater.-

Fig. 6 is a like view, partly in section, of the fourth section of the heater; and Fig. 7 is a top plan of the top section of the heater.

A represents the heater, preferably formed of horizontal sections connected together, mounted on a suitable base B, surrounding any desirable fire-pot, (not shown,) superimposed over a suitable grate C, and surrounded or encircled with any desirable outer casing D. The preferable construction of the heater A, as illustrated, consists of horizontal sections 1 2 3 4: 5, placed one above the other, with water-connections between the heaters, and bolts E, tightly drawing the various sections together. The heater-sections 1 2 3 4 5 are preferably independent of each other, in-" close a separate water-space, and are provided with raised bosses or bearings F at suitable intervals on the adjacent surfaces thereof, having openings or passages G, between which bearings an asbestus gasket or other packing-ring is inserted and the heatersections drawn firmly together by the long bolt E, the lower end of which engages a threaded socket II in section 1 and abuts against a bearing on the top of section 5. By con structing the heater in sections, as described, I greatly reduce the cost of transportation, as the heater is packed and shipped before be ing set up, and the simple construction of the parts allows an unskilled workman to readily assemble the same without endangering the efficiency or operation of the heater.

The sections 3 and a, superimposed above the fire-pot, are provided with inwardly-extending projections or corrugations 7, increasing the space L, formed between the outside periphery of the heater-sections and the inclosing-case D, contacting with corrugations 8, formed on the Outside peripheries of the sections 4, 3, and 2, utilizing all the heat contained in the products of combustion, and

after the same has been conducted around the peripheries of these sections by means of suitable battle-plates 0 they are conducted out by any desirable smoke-pipe M, connected to the space L. It has been customary in heaters of this class to heat the water by means of fines passing through the heater-sections, either welded thereto or formed integral therewith. The arrangement and construction of corrugations on the outside periphery of the heating-sections enable a greater amount of heatingsurface to be exposed to the action of the heat, and at the same time enable the heater to be constructed more cheaply, as my heatersection is readily drawn out without any coping necessitated by flue-spaces, and as the corrugations are preferably rounded the core used in casting the heater-section is readily formed, while when fines were used, if they were cast integral with the heater, it required much more skill to mold the heater-sections,

increasing the expense thereof without obtaining as good results in heating the water. Moreover, to fairly clean these fines and render a free passage to the products of combustion, it was necessary to continue the fines through the top section 5 and provide the same with caps, through which a suitable:

construction, I provide at suitable intervals in the outside casing doors N, opening into the space L and allowing a brush or other cleaning-instrument to be directly contacted with the corrugations on the outside peripheries of the heater-sections. These doors are so arranged that the cleanirig-instrument is also in close contact with the batfie-plate 0, allowing the same to be thoroughly cleaned and the accumulated soot to be brushed down into the lower part of the heater, whence it is readily removed by doors P, opening into the base of the space L. This construction of the cleaning means allows the whole outside surface of the heater to be thoroughly cleansed when desirable and renders a direct contact of the products of combustion with the heatin g-surfaoe, still further increasing the utility of my improved heater. This construction of heater is especially adapted to soft coal or surface-burners, and accordingly I have illusthe other might be increased to any desirable number, and also other changes made in the relative construction and arrangement of the parts without departing from the spirit of my invention.

Having thus fully described my invention, what I-claim as new, and desire to secure by Letters Patent,- is- 1. In a heater, the combination of separate horizontal heating-sections, corrugations on the opposite sides of said sections, openings in said separate heater-sections for connecting the sections one to the other, bearingfaces surrounding said openings for effecting a tight joint, and bolts for drawing together said heater-sections and forming continuous corrugations on either side of the heater, substantially as and for the purpose described.

2. In a heater, the combination of a heatersection 1, one or more heater-sections mount ed above said section 1 and formed with corrugations or projections 011 the outside thereof extending beyond the outside of said heater-section and forming a passage below the same together, bearing-faces surrounding said openings for effecting a tight joint, corrugations formed on the outside of one or more of the heater-sections above the section 1 and forming a space beneath said corrugations surrounding said section 1, a heatersection or steam-dome above the corrugated section or sections, a space interposed between said top and corrugated section and connecting with the said corrugations,whereby the heat is drawn downward therethrough into the space beneath said corrugations, an outer casing surrounding the heater, handholes on said casing, whereby the accumulated soot may be readily brushed downward over the corrugations into the space beneath the same, and a handhole opening into said space, whereby the said soot may be readily removed, substantially as specified.

4:. In a heater, the combination of one or more heater-sections having a plain inner periphery or surface for forming the fire-box and one or more sections mounted above said fir'e-box-inclosing sections, corrugations proward around the heater, and a plain outer face on one or more of said lower sections beneath the corrugations for heating the lower surface of the corrugations, substan- 5 tially as specified.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 8th day of November, 1888.
